Navigating Chicago’s Southwest Side Septic Maze: Your Essential Guide to Gage Park’s Residential Wastewater Requirements

For homeowners in Gage Park and Chicago’s Southwest Side, understanding septic system regulations can feel like navigating a complex web of municipal requirements. Unlike many suburban areas where septic systems are common, Chicago’s urban landscape presents unique challenges for residential properties that rely on on-site wastewater treatment. Whether you’re considering a new installation, facing repairs, or simply ensuring compliance, understanding these regulations is crucial for protecting your investment and avoiding costly violations.

The Regulatory Framework: Who’s in Charge?

In Chicago’s Southwest Side, including Gage Park, septic system oversight involves multiple agencies working together. In Illinois, private septic tank systems at both residential and non-residential properties are regulated by the rules and requirements defined and enforced by the Illinois Department of Public Health (IDPH) and its division of Environmental Health Protection. In Illinois, responsibility for permits and regulatory oversight is handed down to individual health regions and county health departments. For Cook County residents, including those in Gage Park, CCDPH reviews and approves all private sewage disposal systems throughout Cook County; except in incorporated Barrington Hills, Inverness, Palos Park, and South Barrington, which have their own IDPH-approved septic ordinances.

The Chicago Department of Water Management also plays a crucial role, particularly when it comes to sewer connections and stormwater management requirements. Permits are required from the Department of Water Management for the construction, repair, adjustment, rodding or cleaning of any subsurface structure designed to collect or transport storm and/or sanitary waste water, either in private property. Projects that are “Regulated Developments” under the Stormwater Management Ordinance (Chapter 11-18 of the Municipal Code) require stormwater review and approval before a building permit or a sewer permit can be issued.

Key Requirements for Residential Septic Systems

Illinois septic tank regulations are outlined and maintained in the Illinois Administrative Code (IAC) Title 77 Part 905 Private Sewage Disposal Code. For Gage Park residents, several critical requirements must be met:

• Tank Size Requirements: In the State of Illinois, administrative code specifies a minimum size for septic tanks to be used in conventional, gravity fed sewage systems based on the number of bedrooms in a residential home. According to the Private Sewage Disposal Code, a 725 gallon septic tank minimum is required for 2 or less bedrooms, a 1000 gallon septic tank for 3 bedrooms, a 1250 gallon septic tank for 4 bedrooms, and up.
• Mandatory Inspections: An inspection of the septic tank system following construction and before full backfill covering is often mandatory. A mandatory inspection will have to be performed by state personnel and will be an evaluation to ensure the installation followed the planned design without deviation and fully complies with state regulations.
• Regular Evaluations: Private sewage disposal system septic tanks serving residential properties shall be evaluated prior to or within 3 years after the date of installation of the system. The evaluation shall determine whether the tanks and all of the compartments of the private sewage disposal system have layers of scum and settled solids greater than 33% of the liquid capacity of the tank. If the layers of scum and settled solids are greater than 33%, the tanks and compartments shall be pumped out and maintenance shall be performed.

Unique Municipal Considerations for Gage Park

Gage Park’s location within Chicago’s Southwest Side presents specific challenges that homeowners must navigate. The area’s urban density means that septic systems must comply with stricter setback requirements and connection standards. All private drain connections to the City sewer must be made in the street or parkway. All private drain connections to the City sewer must be made in the street or parkway. A minimum spacing of 15 feet between private drain connections to the City sewer shall be maintained, where possible.

For properties considering septic system abandonment in favor of city sewer connections, the existing septic system must be abandoned by pumping out any residual sludge, completely filling the abandoned septic tanks with granular material such as IDOT FA 2 or CA 6, and plugging the ends with grout.

Permit Requirements and Process

Before any septic work can begin in Gage Park, proper permits are essential. Cook County Building and Zoning requires homeowners and contractors to get CCDPH approval before moving forward with home construction projects involving wells and septic. To request a private sewage disposal system review by CCDPH, please submit the following to: Cook County Department of Public Health, Attn: Joe Durczak, 2121 Euclid Ave., Rm. 250, Rolling Meadows, Illinois 60008.

The permit process requires detailed documentation, including lot sketch showing lot dimensions, proposed building location/dimensions, proposed building line and side line distances; street or road names; well location if applicable and well locations on adjacent property; Driveway, patio or other impervious/paved surfaces; underground utilities; plumbing sub out and proposed drain field location; location of easements, wetlands, and flood plains.

Maintenance and Ongoing Compliance

Maintaining compliance with Gage Park’s septic regulations requires ongoing attention. The Illinois Environmental Protection Agency recommends a typical residential septic tank system be pumped every 3 to 5 years depending on the tank size and number of residents. After the first evaluation, the system shall be evaluated a minimum of once every 5 years. Depending on the system’s use, the tanks and compartments may need to be evaluated and pumped more frequently.
